' SORTING MECHANISM FOR CONFECTION WRAPPING'MACHINES.

Original application filed May 3, 1917, Seria1'No. 166,134. Divided andi i :1923. Serial No." 656,508.

ToaZZw/wmz'tmay0011mm; I U Be it known that I. JOSEPH Pnnor REM- INGTON.a citizen of the United States, residing at. Philadelphia, county ofPhiladelphia. and State of Pennsylvania, have invented certain new anduseful Improvements in Sorting Mechanism for Confectionrapping Machines,whereof the following ,isa. specification, reference being bad to theaccompanying drawings. 7 p

. The invention relates to improvements in sorting mechanism for use in.connection with wrapping machines such as shown and described in mypriorPatentNo.1,352,629, dated September 14th, 1920, for improvements inmachines for wrapping confections, and also in my co-pendingapplication, Serial No. 166,134, filed May 3, 1917, for improvements inpositioning and feeding mechanism for confection wrapping machinesofwhich the present application isa division. 1

I The subject matter of this inventionis more particularly directed tomechanism for automatically sorting the articles to be wrapped astheyare beingcontinuously fed to the wrapping devices. i J 5 In order toaccomplish this purpose, the machine constructed according to myinvention includes in connection with means for continuously feeding theconfections,'devices for ejecting confections notproperly positioned forsubsequent wrapping. p The structure ,by which I attain these ends willbe best understood from the drawings, in which+ I I Fig. I, is a planview of a portionof a wrapping machine conveniently embodying myinvention. 1. i

Fig. II, is a sectional elevation of the same as viewed in the directionof arrows II-II in Fig. I..

Figs. III, IV, andV, are detail views on an enlarged scaleof. thetilting devices for the feed belts. v l

Fig. IV, is a detail view'of one of the runways illustrating the methodof guidance forv the confections and also the ejection of an improperlyplaced confection. Figs. VII, VIII, and IX, are cross secthisapplication filed August 9,

t'ions of the same taken respectively on lines VII VII, VIII-VIII, and.IXIX-, ,of Fig. VI. i I

The confections to be wrapped 1 are promiscuously discharged upon an:endless carrier 1, from a suitable hopper or other equivalent 1 1container (not shown). This carrier ismountedupon, and driven byrollers, one of whichis indicated at 2, in Figs; I, and II- i v Thecarrier 1, clined chute 3. Along thischute and overhangingthe dischargeend of the-carrier 1 are theguidestrips 4, spaced toform entrances tothe runways and partitions-be tween them. Below the discharge end of thechute '3, is another. seriesof guiding walls 5, which. accomplish anarrowing of the runways, Corresponding to each of these runwaysisanendless carrier band 6,

discharges by way of an inmountedfat one] end upon a pulley-7, on thesimilar and,ad ustable tensionis put-upon all of the endless bands 6. I

Thesebands 6 pass between "the guiding walls 5, and then across anopening 11,

where theban'ds lack any side protection,

and-'are'sub'ected to tilting means." Extend ing'aoross t is openingimmediately beneath the bands is a rockshaft 12, to the operative crank.13, of which, is pivoted a linlr 15, capas ble ofbeing reciprocated inany well, known manner. Thisrock shaft 12, carries tilting collars 16,set one beneath each band 6. One of these is clearly shown in perspective in; Fig. V. It'is provided with two inclined surfaces1717, onesloping inone direction, and the other inthe opposite, and so related toeach other-thatas the shaft 12 rocks, these inclined. surfaces/17,17alternately push. against the'lower face-of each endlessband 6, andtiltit firstto one side and then to the other. The inclination ofthesesurfaces 17-17, asshown in Fig. III, isinot sufficient to cause aconfection resting upright to tumble off the band 6, but if a confectionhas reachedv said band rest ing upon its side, as shown in Fig. IV, theinclination or tilting of the band 6, due to the tilting collar 16causes it to fall off, dro ping down to a receptacle 20, whenceconihctions may be returned from time to time to the hopper. Theinterruptions in the runways also provide a means of eliminating anexcess of confections, since suchv excess cannot remain on the bands 6where there are no retaining sides to the runwa s. r

.or the remainder of its operative travel, each endless band 6 passesalong'a metal channel 21. Initially, this channel 21 has low edges, asshown at 22-22, in Fig. VII, but first one edge is turned partway over,as illustrated in Fig. VI, at 23, and then the other, as shown at 24, sothat during the latter part of its travel, the band 6 draws theconfections through a partially closed channeled runway of suchshape'that the confections are confined in their lateral movement, sothat they cannot stagger enough to lock, and in their vertical movethetilting collars 16 have for any reason failed to eject mis-shapen orimproperly positioned confections, the turned edges 23, and 24, willinsure this ejection after the manner illustrated in Figs. VI, and VIII.

In dropped goods, notwithstanding the variations in shape to which theyare subject, there is a plane at a determinable height above the base atwhich all the goods have a common cross-section, and the channel 21 isso shaped that the line of contact of the channel sides touches thesides of the con-- fections in this plane.

As the confections pass along the runways, they are subject toinspection, while the rejection of any imperfect or misshaped Iconfections may be thusmanually facilitated if desired.

2 Channels 21, lead directly to a wrapping mechanism not shown, and byreason of the interposition of the devices above described, theconfections are delivered positively in upright positions to theelements by which their envelopment is subsequently efi'ected.

-Having thus described my invention, I claim:

1. In a machine of the class described, a carrier band for conveyingconfections to a point where the are to be wrapped, means for placingcon ections upon the band, and means whereb the carrier band isintermittently incline from the horizontal so that confections whichhave'reached said hand using upon their sides are caused to fall refrom.

2. In a machine of the class described, a carrier band forconveyingconfections to a point where the are to be wrapped, means forplacing con ections upon the band, and tilting mechanism whereby thecarrier band ment so that they cannot capsize. In case is intermittentlyinclined from the horizontal so that confections which have reached saidband resting upon their sides are precipitated therefrom.

3. In a machine of the class described, a carrier band for conveyingconfections to a point where they are to be wrapped, means for placingconfections upon the band, tilting mechanism whereby the carrier band isintermittently inclined from the horizontal so that confections whichhave reached said band resting upon their sides are precipitatedtherefrom, and a runway traversed by the carrier band having means foraligning the confections before they pass from'sai runway. Y

4. In a machine of the class described, a carrier hand for conveyingconfections to a point where the are to be wrapped, means for placingconections upon the band, tilting mechanism whereby the carrier band isintermittently inclined from the horizontal so that confections whichhave reached said band restingupon their sides. are precipitatedtherefrom, and a channel-section runway traversed by the carrier bandhaving'its sides m'erginginto overhanging parallel relation, whereby animproperly positioned confection is ejected and the rest are moved intoaligned relation centrally of the carrier band.

5. In a machine of the class described, a carrier band for conveyingconfections to a point where they are to be wrapped; means for placingconfections upon the band; a rock shaft mounted below the band andprovided with'inclined surfaces sloping in different directions, which,as the shaft rocks, intermittently incline the band first one way andthen the other, whereby the confections which have reached the bandrestin upon their side are caused to drop off sai band.

6. In a machine of the class described, a I

runway for the confections formed by a channel, a part of which near thereceiving end has low longitudinal edges, whereas for the remainder ofitslength the sides overhang sutliciently to reject misplacedconfections, in combination with a carrier band traveling along therunway; and means for 1=ontinuously feeding confections thereto, wherebythe pressure of the on-coming line of confections traveling in therunway causes a misplaced confection which has been halted by theoverhanging sides to be rejected and fall out of the channel.

'7. In a machine of the class described, a combination with a carrierband for conveying confections to a point where they are to be wrapped,of a channel section runway having longitudinal relatively low entryedges merging into overhanging parallel portions, said overhangingportions be- 8. In a machine of the class described, the combinationwith a carrier band for conveying confections to a point where they areto be wrapped, of a tilting mechanism comprising a rock-shafthaving acollar provided with peripheral and reversely inclined projections, andmeans for rocking said shaft whereby the carrier band is intermittentlytilted to the right and left hand relative to its line of travel for thepurpose 1 I specified.

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsyl- Vania, this 7th dav of August, 1923.
